The game was made only for Windows, and has not been tested on Mac OS or Linux, so we cannot confirm whether it works on those or not.It has been confirmed to run properly on all Windows versions, ranging from Windows XP to Windows 10.
Security measures may make installation difficult, though.

8. I can't find my saved games in Windows 10. They're not in the "SAVE" folder. Where are they?(top)

If an application tries to write into a file inside its own installation folder and you are not running it as administrator, the OS may put the file into a virttual store. All reads and writes to the file are redirected by the OS to this virtual store so it's transparent to the application, which is why PoTC still thinks its saved games are in the normal place. This is particularly likely to happen if you installed PoTC into the "Program Files" folder - just one of the reasons why you should install it somewhere else! Try looking in "C:\Users\YourUsername\AppData\Local\VirtualStore\Program Files (x86)\Bethesda Softworks\Pirates of the Caribbean\SAVE". Also look at this thread: Windows 10 getting your saves if game installed in Program Files.

The "Build Mod" is a modpack developed by this community, improving the original game mentioned above by fixing bugs and adding brand new content and features.
It has been worked on by many modders since the original game's release back in 2003, and is still going strong to this day!

Please see this link to our ModDB Downloads page: http://www.moddb.com/mods/new-horizons/downloads
Step 1: Install the original game to any folder outside of Program Files.
Step 2: Place "Part 1: Installation Wizard" in a folder on your computer
Step 3: Place "Part 2: Contents Archive" in the SAME folder
Step 4: Execute the installation wizard, following all instructions carefully.

5. I installed the Build Mod as per the instructions, but now my game doesn't work(top)

Post the .log files from your main game folder in Build Technical.
If there are no .log files, check if Error Logging is enabled:

Changing some values in certain files can cause your game to stop working!
In particular, InternalSettings.h should be editied with caution, and you should always keep a back-up of the original.
If you're the type that likes tweaking multiple files, we recommend keeping a clean back-up of the entire PROGRAM and RESOURCE/INI folders.

B14: Use the Options>Advanced Options menu in the game. Advanced options can be found in PROGRAM\InternalSettings.h
B13: Open BuildSettings.h in your main game folder and make whatever adjustments you want. New game required for some tweaks, but not all.

The original game didn't have sidestep, so we added it. We tried to include collision detection, but failed due to game engine limitations.
Therefore, we have disabled it by default. If you want to use it anyway, set SIDESTEP_ENABLED to 1 at the bottom of PROGRAM\InternalSettings.h .

4. My reputation is horrible. How can I change what people think about me?(top)

7. Since installing the latest modpack, I find that the ships are harder to handle and I have to visit every location for me to fast travel to them, why?(top)

In all releases since Beta 1, we have enabled Realistic Mode by default. This includes counter rudder and having to visit each place in order to unlock Fast Travel.
If you want to fix this, go into Realism Settings (in Options menu) before starting the game and swap Realistic Mode with Arcade Mode.

8. I sometimes get a "using gold" message when opening chests, and I can't open treasure chests; what do I do?(top)

For some reason, this seems to happen when you have the Ammo Mod disabled in Advanced Options. As a temporary fix, you need to enable the Ammo Mod and start a new game.

9. I'm playing a quest and something isn't working, so I can't go any further. What should I do?(top)

It's likely that a quest sequence hasn't been triggered properly, which can sometimes happen at random.
If this happens, you should try reloading a previous savegame. We recommend saving regularly so that you always have something to fall back on.

10. After a while of playing the mod, some things are no longer working properly. What should I do?(top)

If your game has been running just fine until this point, try deleting your "options" file in your main game folder.
This file can gradually become corrupted after playing the game for a long time, to the point where it eventually interferes with performance.
You will need to select your in-game options again, so be sure to take note of them BEFORE deleting the "options" file.

You can customize nearly everything by clicking on it in the Select Storyline interface.
Set ENABLE_CHEATMODE to 1 at the bottom of PROGRAM\InternalSettings.h to be able to choose from ALL ships in the game.
During the game you can buy many outfits at a tailor's shop (pirates only appear for purchase on pirate settlements), and put the outfit on through the F2>Character interface.
To get a unique ship, find Hendrick Vanderdecken in a well known place by getting a well known object from a well known character in another well known place (the ships are highly expensive, though).

FOR CHEATERS AND BETA TESTERS:
Step 1) Open PROGRAM\Console.c and navigate to this section of code used to give you a ship:

Where *MODEL ID* is located in PROGRAM\Ships\Ships_init.c , *YOUR CHOSEN NAME* is the in-game name you wish to give the ship, and *NATION* affects the stats of the model, by determining which nation built it (for more details, refer to the top of PROGRAM\Ships\Ships_init.c).
Step 3) Remove the // from the beginning of the same line.
Step 4) Navigate to this section of code used to change your character:

Step 5) Replace the word "Jack" with the ID of your chosen character, and remove the // from the line.
Step 6) Save the file, start the game, load a new game OR a save game, and press F12. Upon reloading to another location, you should now have your chosen ship and character.

2. For no reason at all my crew morale drops at an incredible rate and mutinies against me (top)

If you have too much money your crew becomes jealous and will become unhappy with you and eventually will mutiny...
To stop this either get rid of/hide your money, pay to raise morale or change the way you're paying your crew, eg. sign articles with them.NOTE: Explanatory note added ingame as per Build 14 Beta 2.5FOR CHEATERS:

To turn off this mod go to the bottom of InternalSettings.h, go to the bottom and change the 0 to a 1 on the line:

- The game now contains a "Profiles" system, which groups savegames together per storyline and profile name.
If you start a new storyline game but already had savegames from a previous time you started that story,
you can create another profile by clicking the "Player" text and typing in another name.

- In Select Storyline, you can choose your player type (Merchant, Corsair, Adventurer, etc.)
This defines which of your skills will increase faster than the others and is indicated with tick marks in F2>Character.

- Hired officers contribute their skills also if they're not in your "active" officer party.
Note that they only contribute the skills that are correct for their type.
In the Passengers interface, you can reassign officers, see their effective skills.
The total effect of player + officers is shown as the player skills in the Passengers interface

- Hiring a doctor with a good defence skill and having medicine on board will decrease after-battle casualties.
Wounded crew are shown as [healthy crew] / [wounded crew] in F2>Ship.

- You can change the appearance of your sails in F2>Ship>Sails.

- You can fly other nations' flags through F2>Relations. If it is a false flag, you can be recognized.
The chance for this increases if you are famous and as you get closer to friendly ships that are of an enemy nation.
Flying your Personal flag, the sea relations will be the same as your real relations.

- If you're confused on island names and positions, consult the Archipelago Map in F2>Inventory>Maps.
You can also buy island maps from the item traders, which will give you town and shore positions and names.

Wind direction has a much bigger impact and you can't sail into the wind any more (in Arcade mode, you can)

Different rig types have a MUCH bigger impact than in Arcade mode

Ships require counter-rudder to stop a turn

- In Arcade mode, based on what spyglass you've bought, they will show:

Nation

Ship name

Ship type

Cannon type of other ship

Hull and sail damage

Number of crew members

Speed

Charge type (eg. balls, chainshot or grape)

There IS an inaccuracy built into these spyglass observations (can be increased or turned off in "Advanced Options"),
but since a real spyglass cannot give you this information at all, in Realistic mode,
your spyglass tells you only other ships' name when they're close, but nothing else.
Spyglasses only enlarge the view (better spyglasses enlarge more) and you have to observe the other ships yourself.
So you'll have to pay proper attention to the other ship's type, colour scheme and flags to define whether she could be hostile or not.

- "Fast Travel" ashore is disabled for most locations, until you manually discovered them by walking through town.

- "Sail To" at sea is disabled for all locationsuntil you've manually discovered them by sailing to them.
The buy-able maps here also unlock Sail To for that island, so that really helps you to find certain shores.

- "Sail To" at sea is disabled for all ships that are too close to you (no instant teleports to right next to the enemy ship)
and also for all ships that, based on your speed relative to the other ship's speed, you cannot overtake.

- Ashore, when there's enemies around, the red flashing icon and danger music doesn't start until they actually draw their swords.
This way, you are not pre-warned of any impeding danger.
